Fairchij: Rainer your timeline spreadsheet should be adjusted to show these warrants at $1.00 Canadian.
Yes, it is difficult to differentiate between CAD and USD, when a Canadian firm makes its financial statements in USD, but is traded at its main exchange in CAD, grants options and issues warrants in CAD, while reporting them in USD. Phew!
Do you (or someone else) have a proper source or sources documenting the exercise prices in CAD of the outstanding warrants, not just the February ones? I'd gladly change/enhance the table to reflect that!
